I am attempting to find the relation between the 5.19 values I receive and the strength of the signal that I input. When I put in a 1 V rms signal I get the values of 0x00, 0x79, 0xdf, 0x6b which when converted from hex to integer is 7987051, but when I put in a .5 V rms signal I get a value of 0x00, 0x72, 0x13, 0xF4, which when converted from hex to integer is 7476212. So the relation between those two values is 0.936 rather than 0.5. Is there some equation that relates these two values?
Any help is much appreciated. Thank you.
